Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a door structure for an automobile, and particularly to an improvement in a door structure that opens and closes a door opening formed from the side to the top of a passenger seat. (Prior Art) Conventionally, there is a door called a gull wing door for opening and closing a door opening formed from the side of the body to the roof.This gull wing door has a door hinge provided on the roof side, and The structure is such that the door can be opened by flipping upwards when it is fully open.Therefore, when the door is fully opened and flips upwards, it cannot be reached by the passenger while sitting in the seat.
A string was hung from the raised door, and by pulling the string, the door was closed. For this reason, conventional gull wing doors have had the problem of poor operability. Furthermore, this gull wing door has a problem in that the distance between the door hinge and the center of gravity of the door is large, resulting in a large operating load when opening the door. In addition, some door structures used in racing cars include a door hinge that is provided near the center of the front edge of the roof in the width direction of the vehicle, and a lower hinge that is provided on a part of the fender that extends to the side of the vehicle body. Such a door structure is arranged so that the door flips up toward the front of the vehicle body and diagonally upward. For this reason, it is difficult for the occupant sitting in the seat to reach the door, and the door is opened and closed by an assistant outside the vehicle. Therefore, such a door structure cannot be used for commonly used passenger cars. Furthermore, as disclosed in Japanese Patent Publication No. 56-28725, the hinge is provided at the center position in the width direction of the vehicle body at the rear of the roof, and the lower hinge is provided at the center position in the width direction of the cowl panel, that is, the width of the front edge of the front windshield glass. There is one that is installed at a forward position in the center of the direction, and a part of the door covers the center of the roof in the width direction and the upper surface of the front windshield glass when the door is fully open.

[Problems to be solved by the invention]

However, in the door structure disclosed in Japanese Patent Publication No. 56-28725, the center of gravity of the door is too far away from the hinge center line passing through the top hinge and the lower hinge, so the operating load when opening the door becomes too heavy. There is a problem. Furthermore, even when the door is open, a portion of the door is above the occupant's head when getting on and off the vehicle, resulting in a narrow space for getting on and off the vehicle.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned conventional problems, and improves the operation when opening a door for opening the frontage from the side of the automobile to the roof.
It is an object of the present invention to provide a door structure for an automobile that can reduce the operating load and increase the space for passengers to get on and off the vehicle.

This invention provides a door opening that is continuously formed in the vehicle body from the side to the top of the passenger seat, leaving a bar roof in the widthwise center of the roof above the passenger seat, and opening and closing of this door opening. an inner peripheral edge of the door opening on the center side in the width direction of the vehicle body, which is a hinge attached to the bar roof, and an inner peripheral edge of the front side of the door opening, which is located between the front pillar and the cowl panel. The above object is achieved by configuring an automobile door structure including a door hinge mechanism that includes a lower hinge attached to a lower position from near a connecting portion of the door, and supports the door so that the door can be opened and closed. Further, the above object is achieved by attaching the flap hinge near the front end of the bar roof. Further, the above object is achieved by attaching the lower hinge to the front pillar at a height of a bent part extending from the inclined part of the front pillar to an upright part continuing below the tilted part. Further, the above object is achieved by installing a gas damper between the front, the lower part of the car, and the front edge of the door near the lower side of the lower hinge. Also, before the door opening! The above object is achieved by forming the J edge along the upper edge of the front windshield glass, the inclined part of the front pillar, and the upright part continuous to the lower side of the inclined part of the front pillar. be. Further, the above object is achieved by attaching the lower hinge to the outer surface of the front pillar in the vehicle width direction, and attaching the tongue hinge to the outer surface of the bar roof in the vehicle width direction. 1 Effect] In this invention, the hinge center line passing through the seven hinges and lower hinge of the door is located at the center of the door body, that is,
Since it is close to the center of the door, the operating load during door-to-door operation is reduced. In addition, since the hinge center line passes close to the occupant seated in the passenger seat, the door can be positioned close to the seated occupant when fully opened. You can easily open and close the door. Further, since the door can be flipped up toward the front of the vehicle body and toward the center in the width direction of the vehicle body when fully opened, there is a large space above the occupant's head when getting on and off the vehicle, and therefore, a large amount of space for getting on and off the vehicle can be taken up.
